Hitachi had to hack it to produce a 500GB 2.5-inch laptop drive, adding another platter (and a few millimeters thickness) that make their new 5K500 impossible to install in most standard laptops and enclosures -- but not Samsung. The Spinpoint M6 500GB drive brings a half terabyte at the standard 9.5mm height, and should land some time in March, meaning your current laptop -- and not just those new Asus machines -- should be able to accommodate one or two of these massive mothers.
